Answer:

A  by 0,5 cubic centimeters

Explanation:

If you use the density equation:

[tex]d=\frac{mass}{volume}[/tex]→[tex]v=\frac{m}{d}[/tex]

For A:

[tex]v=\frac{9[g]}{10g/cm^3} =0,9[cm^3][/tex]

For B:

[tex]v=\frac{4[g]}{10g/cm^3} =0,4[cm^3][/tex]

Doing the difference A-B=0,5 cubic centimeter

Answer:   Object A, by 0.5 cubic centimeter

Explanation:

[tex]Volume=\frac{Mass}{density}[/tex]

Hence volume of object A =[tex]\frac{\text {Mass of object A}}{\text {density of object A}}=\frac{9g}{10g/cm^3}=0.9cm^3[/tex]

similarly, volume of object B = [tex]\frac{\text {Mass of object B}}{\text {density of object B}}=\frac{4g}{10g/cm^3}=0.4cm^3[/tex]

Hence from above :  volume of A > volume of B

Difference in volume =[tex](0.9 - 0.4)cm^3=0.5 cm^3[/tex]

Hence the correct option is Object A has greater volume and  by 0.5 cubic centimeter
